Kubernetes makes it easy to deploy at scale, and just as easy to deploy insecurely at scale. A single over-permissive role, exposed dashboard or privileged container can give an attacker control of an entire cluster. PeakCyber’s Kubernetes penetration testing shows how far an attacker could get from a single foothold.
What is Kubernetes penetration testing?
It is a controlled attack simulation against your clusters, workloads and supporting infrastructure. We test from several starting positions, such as an external attacker, a compromised pod or a stolen service account, and follow realistic attack paths to demonstrate impact.
What we test
- API server and control plane: exposure, authentication and authorization
- RBAC: over-privileged roles, service accounts and cluster-admin sprawl
- Workloads: privileged containers, host mounts, dangerous capabilities and container escape paths
- Network security: network policy gaps and lateral movement between namespaces
- Secrets management: exposed secrets, environment variables and etcd access
- Images and registries: vulnerable images and insecure registry access
- Node and kubelet security and cloud provider integration (IAM roles, metadata services)
- Admission control and policy enforcement
- Add-ons: dashboards, ingress controllers, service meshes and CI/CD integrations
We reference industry guidance such as the CIS Kubernetes Benchmark and the MITRE ATT&CK for Containers matrix.
